Samsung today announced it's mass-producing the first 12Gbit LPDDR4 DRAM chip, which opens the door for 6GB DRAM in mobile devices.

Based on its 20-nanometer-class process technology, Samsung said the new LPDDR4 module is the largest capacity and highest speed available for a DRAM chip.

Compared to the 20nm-based 8Gbit LPDDR4, the 12Gbit version is more than 30% faster, boasting a top speed of 4,266Mbps. It's also twice as fast as DDR4 DRAM for PCs, while consuming 20% less power, Samsung said. PC DDR4 DRAM has a maximum speed per pin of 2,133Mbps.

Samsung said it is also producing 50% more of the new 12Gbit LPDDR4 over its previous 8Gb LPDDR4, which the company believes will fuel demand for higher memory capacity in "flagship mobile devices."

The 12Gbit LPDDR4 chip will be the basis for 3GB and 6GB mobile DRAM in a single package using just two chips and four chips respectively. Previously, 8Gbit DRAM chip technology allowed for a maximum of 4GB in a single module.

"In next-generation flagship devices, 6GB of LPDDR4 mobile DRAM will allow consumers to enjoy seamless multitasking and maximum performance within the latest operating system environments," Samsung said in a news release. "Also, based on the new 12Gb LPDDR4, the 6GB package can easily fit into the same space used for 3GB LPDDR4 packages currently available, therefore meeting the need for greater design compatibility and manufacturing productivity in advanced mobile devices."

Samsung also expects that application areas will expand beyond smartphones and tablets to include ultra-slim PCs, digital appliances and automotive devices, in the coming years.

"We intend to closely collaborate with our global customers to move beyond premium smartphones and tablets in creating new digital markets that embrace the full potential of cutting-edge technologies like next-generation mobile DRAM," Joo Sun Choi, Samsung's executive vice president of memory sales and marketing, said in a statement.
